城市污水土地处理系统中优先有机污染物的生态行为及其调控对策

摘要/Abstract

摘要： 城市污水生态工程土地处理系统是一个多功能、多目标的净化污水, 保护水体实现废水资源化的适用技术系列。如果条件合适, 设计合理, 科学运行和管理得当, 它能对发展经济和保护环境起到积极的作用。应当指出, 优先有机污染物及其生态环境问题可能成为推广应用生态工程土地处理系统的一个限制因素。本文从理论与实践的结合上论述净化功能、生态效应和生态风险评价等一系列复杂的基本性问题, 主要目的是为制定生态工程土地处理系统优先有机污染物的调控对策提供科学依据。

Abstract: Ecological engineering land treatment system(LTS) is suggested as a good pratical technique series with multiple functions and goals in protection of water bodies and purification of municipal wastewater into renew resource under the guideline of ecological principles, and hence, it is a vital area in study of applied ecology. Through optimization of site selection, rational design, good operation and sound managenment as required, it would be able to play an important role in protection environment and promoting economic development. It should be stressed that priority organic pollutants and eco-environmental problems caused by them might be the limiting factor for implementation of ecological engineering LTS in practice. In this paper, a comprehensive review was given on the basis of combination of theory with practice, which covers some essential topics such as purification function, ecotoxicological effects and ecological risk evaluation, etc. However, the main aim is to provide a solid foundation for the effective control and manipulation of priority organic pollutants with LTS.

Key words: Priority organic pollutants, Municipal wastewater, Land treatment system, Ecological behaviour, Ecological effect, Purification function, Ecological risk assessment
